Abstract

We search for the B0→pς¯0π- decay with ς¯0→Λ¯γ, where the γ is not measured, using a data sample corresponding to an integrated luminosity of 711 fb-1 which contains 772×106 BB¯ pairs, collected around the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure for the first time the B0→pς¯0π- branching fraction to be B(B0→pς¯0π-)=(1.17-0.40+0.43(stat)±0.07(syst))×10-6 with a significance of 3.0σ. We simultaneously measure the branching fraction for the related channel B0→pΛ¯π- with much improved precision.
